Hair loss in winter is a natural phenomenon that affects a large number of people. This hair life cycle is often influenced by climate changes and external aggressions. The cold, dry air due to heating, and a lack of nutrients can lead to seasonal hair loss. Fortunately, there are tips to limit these effects and preserve the health of your hair. In this article, we reveal all the keys to understanding the reasons for this hair loss and effectively remedying it.
Why is hair loss common in winter?
The effects of cold on the scalp
In winter, the cold slows down blood circulation in the scalp. This decrease in blood flow directly impacts hair growth. In fact, the hair follicles receive less oxygen and nutrients, which weakens the roots and causes hair loss. In addition, the cold causes a decrease in the secretion of sebum, a natural element that protects the scalp and lengths against dehydration.
This situation makes hair drier, brittle and vulnerable. The hair life cycle, which includes growth, rest and shedding phases, can then be disrupted, which intensifies loss during this period.
Impact of dry air and heating
Dry air caused by heating systems is another major factor in hair loss in winter. By drying out the indoor atmosphere, heating strips the scalp of its natural moisture. Hair becomes more fragile, duller and more prone to breakage.
Excessive use of the hair dryer during this season also contributes to the drying out of the hair. If you add to this the temperature differences between the heated interior and the cold exterior, the hair suffers an impact that can alter its natural cycle.
Seasonal changes and their influence on hair cycles
Seasonal changes strongly influence hair cycles. After autumn, when hair loss already peaks, winter prolongs this resting period for hair follicles. This is due to the body's natural biological rhythm that adapts to the seasons.
During this phase, the hair enters a resting state to prepare for regrowth. This phenomenon is perfectly natural, but it can be accentuated by other factors such as stress, reduced exposure to the sun, or a lack of essential vitamins.
Tips to limit hair loss in winter
Adopt a suitable hair routine
A suitable hair routine is essential to limit hair loss. Start by choosing gentle shampoos, without sulfates or parabens, which do not attack the scalp. Use a moisturizing conditioner and regularly apply nourishing masks rich in fatty acids.
Brush your hair gently with a natural bristle brush to avoid damaging it. Reduce the use of hair dryers. These simple steps protect your hair from external aggressions.
Maintain good scalp hydration
To prevent dry scalp, rely on natural oils like coconut oil or argan oil, rich in essential fatty acids. Gently massage the scalp to stimulate blood circulation and nourish the roots.
Remember that hydration also comes from within. Drink at least 1.5 liters of water per day to maintain the health of your hair.
Protect your hair from external aggressions
Wearing a wool/cotton hat helps protect your hair from the cold. However, it is important to choose soft materials to avoid excessive friction. Alternate between days when you cover your hair and days when you let it breathe.
Diet and hair loss: what to prioritize in winter?
Essential Nutrients for Strong Hair
Diet plays a central role in hair growth and regrowth. B vitamins, especially vitamin B group B, as well as sulfur amino acids, promote the production of keratin. Fatty acids and vitamin C are also essential for maintaining strong and shiny hair.
Examples of foods to incorporate into your winter routine
Eat oily fish (salmon, mackerel, sardines) for their omega-3 content. Seafood like oysters and shrimp are rich in zinc, a key element in preventing hair loss. Brewer's yeast, a natural source of B vitamins, is also ideal for strengthening your hair.
Importance of dietary supplements, if necessary
In case of deficiencies, dietary supplements can be helpful. Formulas containing brewer's yeast, iron or vitamins are often recommended. These supplements help regulate the hair cycle and prevent seasonal alopecia.
When to consult a specialist?
Signs of Excessive Hair Loss
If the loss exceeds the average of 100 hairs per day, it is time to consult. Other signs such as bald areas, an irritated scalp or a lack of regrowth should alert you.
Medical solutions and adapted treatments
Treatments such as stimulating lotions or mesotherapy can help reactivate growth. Medical examinations can also identify underlying deficiencies or diseases.
Role of dermatologists and trichologists
Many specialists, including dermatologists and trichologists, recommend a personalized approach to treating hair loss. According to Ludovic Rousseau, a recognized hair health expert, hair loss in winter should not always be a cause for panic, as it is part of a natural life cycle. However, a consultation becomes essential when this hair loss intensifies or persists.
He also emphasizes the importance of combining simple actions, such as a balanced diet and appropriate care, to prevent seasonal hair changes.
Conclusion
Hair loss in winter is a natural phenomenon linked to cold, seasonal changes and other external factors. By adopting an appropriate routine, taking care of your diet and consulting if necessary, you can preserve your hair.
